【技术实现步骤摘要】
本技术涉及除尘设备,特别涉及一种带有保护功能的除尘器。
技术介绍
现有技术中的除尘器,在正常工作情况下,含尘烟气经过滤袋过滤区过滤后,洁净气体通过净气室的离线口由设备本体烟气出口排出,离线气缸根据过滤阻力进行压紧阀板与提升阀板的操作,当离线气缸出现故障时,除尘器处于封闭状态,除尘器后面的风机因此而发生运转停止,除尘器前面的锅炉会出现正压影响锅炉的正常运行甚至停止运行,从而发生危险。
技术实现思路
本技术的目的在于克服上述技术的不足,从而提供一种带有保护功能的除尘器,通过开设旁通口以及设置旁通阀板能够防止危险发生。技术所采用的技术方案是这样的:带有保护功能的除尘器,包括除尘器本体,所述除尘器本体内设置有尘气室、净气室以及排气室,所述尘气室连通有烟气进口,所述尘气室与所述净气室之间通过滤区相连通,所述尘气室与所述排气室通过旁通口相连通,所述净气室与所述排气室通过离线口相连通,所述排气室连通有烟气出口,所述离线口处设置有离线阀板,所述离线阀板由离线气缸驱动,所述旁通口处设置有旁通阀板,所述排气室的内壁上垂直设置有圆柱形悬吊杆,所述旁通阀板设置有与所述圆柱形悬吊杆相配合的滑动轴承,所述旁通阀板上开设有供所述圆柱形悬吊杆穿过的穿孔,所述圆柱形悬吊杆上套设有压簧,所述压簧位于所述旁通阀板与所述排气室的内壁之间。进一步改进的是:所述圆柱形悬吊杆的下端部设置有防止所述旁通阀板与其相脱离的限位部。进一步改进的是:所述过滤区设置有若干布袋除尘器。进一步改进的是:所述滑动轴承与所述旁通阀板之间设置有气密垫圈。通过采用前述技术方案,本技术的有益效果是:当离线气缸出现故障时,离线阀板处 ...
